OPERATING AND SETTING UP INSTRUCTIONS
INTRODUCTION
This manual contains instructions for operating as well as lubricating and installing the International 1501 Front Mounted Loader on either the International B 275 or B 414 Tractors.
If you should need information not given in this manual or if you should require the services of a trained mechanic, get in touch with the International Harvester Dealer in your locality. Dealers are kept informed On the lat es t methods of
servicing our equipment. They carry stocks of L H. parts and they are backed in every case by the full facilities of a nearby Internationa l Harvestel' District Office. •
Throughout this manual. the use of the te rms LEFT and RIGHT, will indicate the left and right side of the machine when sitting in the Operator's seat facing fron t. FRONT is the radiator end of the tractor and REAR is the draw ba r end
ADJUSTING AND OPERATING INSTRUCTIONS
The 1501 Loader uses single del'S for raising the boom.
Either the 40" Manure Bucket or the 40" Material Bucket can be equipped with the mechanical latch buck et trip or the double acting hydraulic cylinder bucket controL
NOTE: When it is necessary to lift a heavy lo ad to a high position and then lower it to another position before dumping, be sure to operate the
MECHANICAL LATCH BUCKET TRIP
control valve very carefully Do not suddenly thrust the valve wide open and then jerk it completely closed The heavy load will gain momentum downward when the control valve is released; then when the valve is suddenly closed the loader's mechanical travel is halted, but the momentum of the heavy load applies high stresses to boom arms. Overcome this by slowly opening or dosing the control valve, this will release or retard the fluid gradually and by doing so. will ease the load to the desired position , instead of dropping or bounciug it.
must. 3A
After the boom is raised. the bucket can be dumped instantly by moving the bucket release h andle toward the rear The handle is spring loaded and will return to its original position when released . The bucket is free to swing and should return to the latched position. however, i f for some r eason it does not. lowering the bucket to the ground will latch it automatically.
The pitch of the bucket may be changed to suit various digging conditions Three positions

are provided on the bucket side. The center position will set the bucket level with the bucket at ground level, the front position lifts the front of the bucket off the ground, wh erea s, the rear position tips the front of the bucket downward. To change the degree of the bucket, simply pun out the quick -attaching cotter pin, remove the tapered end pin, move the ro ller to the desired position and replace the pin and cotter. Be sure the pins are in corresponding ho le s on both sides of the bucket, Illust. 3A.

HYDRA ULIC BUCKET CONTROL
HYDRA ULIC SYSTEM
Use hydraulic fluid in the system as recommemled in the Tractor Operator's ManuaL Wipe away all grease and dirt before removing filler caps, plugs or other parts requiring service
Plug all open ports so that dirt cannot enter, as dirt is injurious to the pump and valves Wash all parts to be reassembled thoroughly in solvent.
NOTE: When the loader is to be removed from the tractor. and is not to be used for a period of time. i t is recommended that lubricant be applied to any exposed surface of the piston rods.
If your tractor hydraulic pressure lines have been reworked to use the hydraulic bucket control and you wish to disconnect your loader, a tractor pressure line coupling is supplied with each hydraulic bucket controL Refer to Illust. 4B.
must 4A H 8342
The double acting hydraulic bucket control cylinder is activated by a single spool, four-way valve which is set for a pressure of 2400 P . S . 1. at 7 gallons per minute Moving the valve lever forward dumps the bucket, while rearward motion of the lever angles the bucket upwards.
"VHEEL TREAD
Adjust the rear wheels to not less than SO-inch tread.
Adjust the front wheels to approximately 58 -inch tread. Refer to your Tractor Operator's Manual.
BALLAST
Up to 1 000 pounds weight may be added on the 3 point hitch linkage at the rear of the tractor to counterbalance the weight of the loader. Rear mounted equipment can also be used as ballast.
TR1'\CTOR SLIPPAGE
Tractor slippage can be overcome by adding water or calcium chloride solution in the rear tires, or adding rear wheel weights Refer to your Trac t or Operator's Manual.
OPERATING SPEED
The tractor may be operated at full throttle for normal operations. When working over rough terrain or in limited working space , reduce engine speed accordingly.
Place the tractor in first gear when digging or performing heavy operations . Second gear may be used when loading. levelling or grading.
TRANSPORTING
When transporting, roll back the bucket or latch it and raise the boom to give the same ground clearance as provided by the tractor while still carrying the bucket low enough for ade q uate visibility
ADDING FLUID AFTER CONNECTING CYLINDERs AND HOSES
Start the engine and operate it at a moderate idle speed and operate cylinder pistons to their maximum stroke in both directions about ten times This will rill the cylinders and hoses with fluid and remove air from. the system.
Set the cylinder pistons in the retracted position (all the way in). If necessary, add fluid up to the proper level. Refer to Tractor Operator's Manual.
FILTER SERVICE
Disregard the intervals for cleaning the screen and replacing the filter elements in your tractor manual when operating the loader and use the following instructions :
When starting a new unit, clean the screen and replace the elements after the first 50 hours of operation and every 100 to 200 hours thereafter . dependi.ng on the nature of use of the loader. Dusty climates and material require more frequent filter changes . Service intervals can best be determ.ined by the individual operator. See the Tractor Operator'S Manual for removal instructions; also instructions to check the fluid level. When reusing fluid, be sure to filter it thoroughly so that dirt is not introducted into the system
Always have the cylinders retracted when checking the fluid leveL
A clogged filter will be indicated by one or more of the following:
Noisy pump
Overheating
Loss of power
Slow and erratic operation
COLD WEATHER STARTING
Warm the hydraulic fluid by running the tractor engine at idling speed for several minutes before operating the loader cylinders
